Silver Series Jet Pumps Manual Pressure Pump Model SJ35-04 Automatic Water Pressure System Models SJ35-04P2C/LOP, SJ35-04PC & SJ60-08PC Installation & Operating Instructions Please pass these instructions on to the operator of this equipment.
Congratulations on your purchase of a Silver Series quality pressure pump or water pressure system. All components have been designed and manufactured to give trouble free, reliable operation. Before installing your new pump, please read all instructions carefully as failures caused by incorrect installation or operation are not covered by the guarantee. Your SJ Silver Series Jet Pump is designed to handle clean water. The pump should not be used for any other purpose without specific referral to Davey.
Power Connection The pump motor is fitted with an earthed three pin plug & lead. The installer is responsible for the correct connection of the electrical supply to the pump motor. • Make sure the supply voltage and frequency is the same as the nameplate. • Make sure that there is a sound earth connection available. In accordance with AS/NZS 60335.2.41 we are obliged to inform you that this pump is not to be used by children or infirm persons and must not be used as a toy by children.
Abrasive Materials The pumping of abrasive materials will cause damage to the pump which will then not be covered by the guarantee. Water temperature in pump must not exceed 45oC, or damage caused will not be covered by guarantee. Connection of Mains Scheme or Town Water Supply to either Suction or Discharge of Pump Most Water Supply Authorities have strict regulations regarding direct connection of pumps to mains water supplies. In most cases an isolating tank is required between mains supply and pump.
Priming and Operation continued... SJ35-04 PC & SJ60-08PC Automatic Water Pressure System 1. Fill pump and suction line through the pump discharge or priming port (on flooded suction, simply open gate valve to pump). 2. Ensure outlet nearest to pump is open. 3. Ensure all valves in suction line are open and switch on pump at power outlet. There will be a delay of less than 1 second before the pump starts. 4.
Pressure Tank Maintenance (SJ35-04P2C/LOP only) The only regular attention your new pressure system requires is to check the pressure tank’s air charge every 6 months. This is ‘factory set’ at 125kPa (18psi) and can be checked at the air valve with a tyre gauge. CAUTION: Do not charge tank to a higher pressure than 125kPa. To check air pressure in tank: 1. Switch off pump. 2. Open outlet nearest to pump to release water pressure. 3.
Trouble Shooting Check List continued... PUMP STOPS, BUT RESTARTS QUICKLY - NO FLOW DEMAND (AUTO MODELS ONLY) 1. Leaking suction line, checkvalve or footvalve. 2. Suction pipe too long and/or too flexible. PUMP DOESN’T SUPPLY ADEQUATE PRESSURE 1. Suction lift is too high. 2. Pump impellers partially blocked. 3. Jet blocked. 4. Partially blocked suction line. 5. Wrong pump selected. 6. Change the installation. NOTE: For protection, the pump motor is fitted with an automatic “over temperature” cut-out.
